well, I can say that having quite a bit of experience with both, that CHAdeMO is huge, clunky and prone to breaking. It's not user friendly, so much so, I don't believe it is ready for prime time, not ready for the mass market of non-EV enthusiasts who are simply happy to have anything beside L2. it got so bad with the Leaf that I just stopped trying to go beyond the Leaf's range on a single charge, along with a whole lot of other people. We have many, many ChadeMO chargers in the Northwest and it's really astonishing how few of them work reliable. I hear of very few Tesla Super Charger issues.
Re: CHAdeMO being huge, clunky and prone to breaking. Yes, the cable and connector are heavy and the early (still in use) Yazaki handles aren't intuitive, at least not w/o reading instructions and/or watching videos first. And, yes, I hear that someone CHAdeMO DC FCs end up being out of order due to broken handles.
Reading the directions on the side of the stations while waiting for a charge and watching How To Use a Yazaki CHAdeMO Connector - YouTube
made things MUCH easier for me.
The only CHAdeMO DC FC I've used has a Yazaki handle very similar to the one in the video except that there's a spring loaded charging lock for the black handle that needs to be pulled back too. IIRC, to detach, you have to pull the black handle slightly, pull the charging lock back and push the black button.
Again, not intuitive, but now is a total piece of cake once you've seen instructions and/or watched video then done it once.
